It is not a map, but Samos->Delphi->
Kroton is on a straight line (calculated from latitude and longitude);
Also, Delos,
Delphi and
Metapontum are on a straight line (well, 1/2 degree off).
Pythagoras moved from Samos to
Kroton,
Delphi of course, was the center (
omphalos) of the world and very important to Pythagoras. The oracle was called the Pythian oracle, and Pythagoras was said to speak publicly like the Pythian oracle (Pythios-agorein). In fact, he was said to _be_
Apollo, and when he moved to
Metapontum, he created another chain, Delos is the birthplace of
Apollo,
Delphi is the site of the mature
Apollo, and when Pythagoras died in
Metapontum, he made it the death place of
Apollo.
But don't take my word for it, look up the poleis (cities) on
Wikipedia, get their latitudes and longitudes and find an airplane website for mapping from point A to point B.
I cannot
help but believe that Pythagoras knew what he was doing moving from one end of the Greek world, to the other end, Samos to
Kroton, with a consultation at
Delphi, but also Delos, where he was said to have buried
his teacher, Pherecydes of Syros, to
Metapontum, to where he
had his apotheosis,
Metapontum. Did he have access to Anaximander's map? or the bronze map of the Milesians (which perhaps are one and the same)?
Maybe there was more to the map than we usually recognize, oh sure, maybe at the borders it gets vague, and it says 'past this point there be dragons (or gold guarding griffins and giant ants), but for the Greek world, maybe they
had some idea of the lay of the land, and Pythagoras used that knowledge to orchestrate
his prophetic arrival.
